7*IHRE FABRIC.

Application led September 26, 1921. Serial No. 503,209.

To all whom 'it may concern:

Be it known 'that I, Hanni' M. YOUNG, a citizen ofV the United States,residing at the city of St. Louis, State of Missouri, have invented acertain new and useful Improve ment in Wire Fabrics, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

This invention relates generally to wire fabrics and, more particularly.to a certain new and useful improvement 1n wire :tabrics oflthe knit-tedtype especially adapted :tor use in the production of spring-mattressesfor beds and the like, the principal object of my present inventionbeing to provide a single wire knitted fabric whose construction issimple and inexpensive and which will minimize sagging or `distortionunder` With the above and other objects in view, my present inventionresides in the novel features of form, construction, arrangement, andcombination of parts hereinafter described and afterwards pointed out inthe claims.

In the accompanying drawing,

Figure l is a plan'view of a spring-inattress embodying' a section otknitted wire fabric constructed in accordance with my invention; and

Figure 2 is a longitudinal sectional view of the mattress and' fabrictaken approximately on the line 22, Figure 1.

:ReferringT now more in detail to the said drawing, which illustrates apracti 'al cmbodiment. ot my invention and in which like referencecharacters refer to like parts throughout tlie several views, Adesignates the single wire. or strand o'l the knitted portion of thestructure, whose terminals B and C are relatively fixed, and which isfabricated as by knittinw to form an approximatetxv square mesh oodycomprisingA loops D in spaced parallel rows extending in one directionor longitudinally of the fabric, and loopspacing strands or laterals Eextending at a right angle to the loops D, whereby each inside mesh ofthe fabric, that is to say, each" of the meshes of the fabric except atthe longitudinal and lateral sides thereof, comprises a pair of theloops D and a pair of the spacing` strands E.

Each so-called inside loop D comprises integrally a relatively sharpbight l, e, pair oit' suitably elongated legs or longitudinals 2-2extending in approximately straight lines Afrom the bight l, andoppositely disposed turns or bends B--l at the ends ot' each leg orlongitudinal 2 opposite the big-ht l, each intermediate loop ot' a row,that is to say, cach loop ot' a row except the end loops of the row,havingengagement at its bight with the bends of the next adjacent loopot' such row.

Each loop-spacing strand or lateral E consists ot a single length orsection floi" the wire integrally extending,r in an approximatelystraighttline between spaced pairs of the turns or bends 3 ot the loopsD,

As so fabricated, the fabric as a wholel is bounded at one longitudinalend by a ma gin coinprisinpr the bights 1 ,of a series ot' the spacedloops D; at its opposite longitudinal end by a marfrin comprisingv thebends or turns 3 and thc loop-spzminpr strands or laterals 4 opposic thebigrhts l; at one lateral sideby a margin comprising.,r the terminals Band t" bights l. and loops F, the latter being substantially like themain body loops D, with thc except ion, however, that its one leg 2 isot' double the length of the corresponding leg' ol' the loops D in thebody oi: the fabric, whereby its bight l and bend or turn f5 are spacedby a length comprehcnding three of the llaterals e, and its other leg 2isjoincd by an oblique lateral 4 to the next row of loops D; and on theother lateral side by a substantially similar side margin comprisingsimilarly extended legs Q. all as best seel'i in Figure l.

The fabric, knitted of a single wire to thgis comprise straight lines inboth the'longiitudinuls and latcrals, as distinguished from thcsubstantially circular loops iu rows or chains. as is common to thepresent knitted fabrics. is one which may uol only bc readiiv tabricawl.but which will also be practically frcc from distortion or strhtchingi'.

The supporting struct urc for my ncw fabric t'or its adaption for use ina springmattrcss. bed.y or the like, comprises heads 5 and rails (lsuitably secured together and which l prefer to construct oi' angleiron. as shown. To the heads are attached a number otcoil-springs 7 orothcr suitable yield,- ing members, the springs i' at one longitudinalend being secured in the biffhts 1 of the loops D and the otherlongitudinal enti en gaging around the bends or turns 3 between the legs2 of the loops D and the loop-spacing strands et. In this manner, therows or chains of loops D and the series of laterals E are yieldinglysupported relatively to the i Y heads 5.

i 1 the knitted fabric as a whole is suitably secured. Obviously variousmeans may be conveniently employed for such purpose. Inl/the presentinstance, l employ for such ur ose as shown the securing-bands or` y D"ilii/iks/l() engaging the fabric and the rail 8 time side margin and atthe other side /inatrgin engage the fabric with the rail 8 by, I

,'intthe assembling of the spring-mattress or bed, inserting the railthrough the edgeloops F between their elongated legs 2' and the obliquelaterals 4. In the present instance, l have also shown the terminals Band C 0f the fabric as secured, and thereby fixed, in the springs 9, butobviouslyy the terminals of the fabric may be otherwise relativelyfixed, as, for instance, to the body of the fabric itself or to thesag-rail, and other changes in the form, construction, arrangement, andcombination of the several parts of my fabric may be made andsubstituted for those herein shown and described without departing fromthe nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure byLetters latent is:

l., A substantially square-mesh knitted fabric constructed of a singlemetallic wire and integrally including a plurality of longitudinal rowsof loops and a plurality of laterals for spacing the longitudinal rowsof loops, each inside loop of the fabric including a bight, a pair ofsubstantially parallel legs extending in approximately straight linesfrom the hight, and oppositely disposed bends at the end of each legopposite the bight, and each lateral consisting of a single lengthextending inA approxi mately a straight linebetween pairs of the bendsof the loops, each intermediate loop of'a row extending at its bightunder the legs and over the bends of the next adjacent loop in such rowand each outside loop at name to this specification.

insane? the lateral sides of the fabric having one leg of a lengthdouble the length of the other leg thereof, each inside mesh of thefabric comprising a pair of loops and a pair of the loop-spacinglaterale, some of the later-als at onelateral side of the fabricbeingobliquely disposed to the remaining laterals and providing open sag-railaccommodating edge loops at said lateral side of the fabric.

2. A substantially square-mesh knitted fabric constructed of a singlemetallic Wire and integrally including a plurality of longitudinal rowsof loops and a plurality of laterals for spacing the longitudinal rowsol' loops. each inside loop of the fabric including a bight, a pair ofsubstantially parallel legs extending in approximately si rai glu linesfrom the bight, and oppositely disposed bends at the end of each legopposite the bight, and each lateral consisting of a single lengthextending in approximately a straight line between pairs of the bends ofthe loops, each intermediate loop of a row extending at its bight underthe legs and over the bends of the next adjacent loop in such row andeach inside mesh of the fabric comprising a pair of the loops and a pairof the loop-spacing laterals, some ol the laterals at one lateral sideof the,

fabric being obliquely disposed to the remaining laterals and providlngedge loops at said'lateral side of the fabric, in comj bination with asupporting structure coinprising suitably connected end and side bars,springs engaging one end bar of the siipporting-structure and the bightsof the adjacent end row of loops, springs engaging the opposite end'barof the supporting-structure and the bends of the opposite end row ofloops, a sag-rail attached at one lateral margin of the fabric to theopposite end-bars of the supporting structure, links having engagementwith said sagrail and with the outside rows of loops upon said lateralside of the fabric` and a second sag-rail projecting lengthwise throughsaid edge loops upon the other lateral side of the fabric and alsoattached at its ends to the opposite end-bars of the supporting structure.
